Summary
Plasma HCS levels have been determined in a number of physiological situations. The half-life was found to vary between 10·8 and 20·2 minutes. Variation of HCS levels during labour was no greater than that during 24-hour periods in late pregnancy. There was an increase in levels at the time of delivery. In late pregnancy, 5 out of 10 subjects showed variation during a 24-hour period, but this variation did not follow any recognizable pattern.
